Buffon's Needling Ants - Ivars Peterson (MathTrek)
The idea of estimating pi by randomly casting a needle onto an infinite plane ruled with parallel lines was first proposed by the naturalist and mathematician Georges Louis Leclerc Comte de Buffon (1707-1788). In recent years, computer
simulations have
